JUICE EXTRACTR.

Application :tiled August l, 1920. Serial No. lloll'.

To aZZ whom t my concern Be it known that l, MANUEL ROSENFIELD, a citizen of the United States, and a residentof the city of Alameda, county of Alameda, State of California, have invented lmprovements in Juice Extractors; and l do hereby declare the following to be a full, clear, and exact description of `my invention, such as Will enable others skilled in the art to which it pertains to \make and use the same. n

This invention relates to a device lor entracting the juices trom fruits for use in making refreshments, preserving and the like, and the invention aiins to provide a device of that character having novel and improved features of construction which render it particularly suited and ellicient for the intended purposes.

Another object is the provision ot such a device having means above a tabletop :flor acting on the fruit, `with actuating means lo` cated under said tabletop, said means being protected, and means being provided :tor delivering-the juices into receptacles.

A 'further object is the provision of a novel rneans for extracting the juices 'from citrus fruit, such as oranges, lemons, grapefruit, etc.

llhe invention is illustrated in 'the accompanying drawings, wherein:

'Figure l is a view oi2 the device, partly in` elevation and partly in section substantially onv the line lef-l ol llig, 12.

Figa 2 is a plan view showing the hood in section on the line 2 Q of' Fig. 3.

3 is a. vertical transverse section on the line 8 3 of 2.

l suitable base l is provided nhzei housing 2 is mounted, which is onen at tl f i ,A

il@ rear for access to the parts Within the nousine. A table top 3 is disposed on e lionsi and has a longitudinal repression i a trough sloping' to one end the lio singg and longitndin bosses 5 rise troni the bottoni or" and provide b nrings a *da f oi f* s il which e r supporting l ions 8 are secured to the lower ei i spindles Within the lionsinfr said spindles, as Willlierei appear. Thenpper 'the juice cells et halved citrus dles are tapered, as at 9, and of square or other non-circular cross section.

Above the trough d and bosses 5 are disposed a pair or cups l0 havingradial slits 1l in the bottom thereof and central hubs il mounted loosely on the collars 7 and seated on the bosses 5, whereby said cups are conveniently supported with the upper terminals of the spindles projecting upwardly centrally Within the cups. rlhe cups may turn, although they Will stand still it' touched by the hand or lp-ruit. ithin each cup there is disposed the abrasion conoid or bulb l2 having1 a downwardly opening socket l2 to receive the upper terminal the spindle., for rotating the conoid with. t' spindle, and the periphery of the col, is toothed or corrugated for gol the lilre. Each conoid l2 has i il for scraping or ren'izn'ing1 the l or pulp oi' the fruit from the eo` i shells., i'

is yieldingly moved toward or against theroll 19, so that the, fruit which is placed in the hopper will be crushed in assing downwardly between the rolls. tar gears 22 are secured on the shafts 18 and 21 and work cured to the' other end ofthe shaft 18 and extends through the slot 14 to mesh with a inion 24 within the housing 2 secured on a short shaft 25. A clutch 26 is employed for connecting the shaft 25 with a drive shaft 27 which is in alinement with the shaftv25, and said shafts are mounted in bearings 28 supported from the front wall of the housf ing 2.

The clutch 26 is opened and closed by a lever 29 supported from the tabletop 3 and .extending to the rear for convenient operation.

The fruit juice extractors are driven from the shaft 27. Thus,l bevel gears 30 arel secured on the shaft 27 and mesh with similar gears 31 Vsecured on transverse shafts 32 which have bevel gears 33 with which the bevel pinions'8 mesh. The spindles 6 are thus rotated by the shaft 27, and the fruit crusher is rotated from said shaft whenever the clutch 26 is closed, the Crusher being stopped when the clutch is opened. The shaft 27 is connected by a sprocket chain 35 or otherwise with an electric motor 37 mounted in the housing 2.

A wire mesh screen 38 is inserted under.

the crushing rolls 19 and 20, for catching the pulp or solid material of the crushed fruit, and the juices pass down through the screen into a trough 39 disposed under the screen and rolls and sloping opposite to the trough 4 and extending through the end of the housing opposite to the end to which the trough 4 extends. A cup'screen or strainer 4() is suspended from the projecting end or spout of the trough 39 on the exterior of the housing 2, through which the juice flows from the trough or spout into the receptacle v 41. The housing 2 has shelves or brackets 42 at the opposite ends for supporting the 50. delivery spout flows into the receptacle 41 at one end, while The juice from the Crusher invasa@ and the hood, like the housing 22 is Aopen at the rear, so' that access into the hood from the rear can behad for placing the fruit into the hopper`\15 and cups 10.

Having thus described my invention, what I desire to claim and to secure by Letters Patent is z-f 1. A device of the character described comprising a bearing, an upstanding spindle extending through said bearing, a cup having slits in its bottom and having a central portion loosely and removably disposed around the spindle and seated on said bearing, means for catching liquid .dripping from the Hcup around said bearing, and an abrasion member removably fitted on the spindle within saidcup.

2. A device of the character described comprising a bearing, a'sspindle extending upwardly through the bearing, a collar on the spindle seated on said bearing, a cup having slits in its bottom and a central hub fitted on said collar, and an abrasion mem# ber fitted on the spindle within said cup.

3. A device of the character described comprising an upstanding spindle, a cup rei kmovably fitted around the spindle and hav- -ted loosely on said collar, and an abrasion member fitted removably on said spindle above the collar and having a radial fluke.

In testimony whereof, I have signed my name to this specification i'n the presence of a subscribing witness.'
